Maternal behavior as a regulator of polyamine biosynthesis in brain and heart of the developing rat pup.

Rat pups removed from the mother and placed in a warm incubator for 1 hour or more show a 50 percent reduction in ornithine decarboxylase activity in the brain and heart. The decline is not caused by lack of nutrition. Instead, these studies suggest that active maternal behavior is necessary to maintain normal polyamine metabolism in brain and heart of the pup during development.

Genetic and ethanol-related differences in maternal behavior and offspring viability in mice.

Primiparous female mice of 2 lines genetically selected for different narcotic responses to ethanol were administered 10% (v/v) ethanol in their drinking water during Days 2-14 of lactation. Ethanol treatment resulted in a marked decrease in growth and viability of pups in both lines. Fewer offspring of the ethanol-sensitive line survived to weaning, apparently because of the failure of a large number of dams to exhibit maternal care. The combination of ethanol treatment and an additional environment stressor (mouse hepatic virus) had a devastating effect on maternal behavior and offspring survival in the ethanol-sensitive line, but far less effect on the ethanol-insensitive mice. Thus, ethanol-sensitive animals appear to be more susceptible to a variety of stressors, including ethanol.
